Password Protected Relay based PC Controlled Wireless Home Automation System with ATmega16 using HC-05 Bluetooth-II Project Kit is a kind of Secured Wireless Home Automation Kit where different home appliances like Bulb, Fan, TV and others are controlled wirelessly from a PC through Bluetooth. For controlling different home appliances, here we are using relay.

Before any home appliances can be controlled, a password needs to be entered into the Home Automation system to gain access of appliance control. After the correct password has been entered, the appliances can be controlled else the system keeps asking for the password. The home appliances can be controlled wirelessly by sending predefined characters from a PC through Bluetooth. Here, we will control 4 appliances, two Bulbs and two Fans. For each home appliances, one character is assigned, each time the key is sent, the appliances changes its status i.e from On to off and from Off to On. Apart from these characters, two more characters are assigned, one to turn-on all appliances at a time and the other to turn-off all appliances at a time. So, all total 6 keys are used to control 4 appliances(Two Bulbs and two Fans). The control characters for 4 appliances are shown below:-
